T 0 all whom it may concern:

Be it known that I, J OHN BAILEY BirowN- ING, a citizen of the United States, residing at the city of Camden, in the county of Camden and State of New Jersey, haveinvented new and useful Improvements in Talking-Machine Cabinets and Amplifiers, of which the following is a specification.

My invention relates more particularly to sound reproducing or talking machines having an enclosed horn or amplifier to which the sound is transmitted through a suitable sound conduit from the sound-box or sound reproducing means.

In the drawings: Fig. 1 1s a sectional side elevation of a machine embodying my invention; Fig. 2 is a front elevation of the same on a reduced scale and with the front doors open; Fig. 3 is a rear elevation; Fig. 4 is a vertical section of the collar for securing the horn section to the opening in the "back of the cabinet; Fig. 5 is a side elevat-ion of the turn-table brake; Fig. 6 isa plan view of the brake escutcheon; Fig. 7

1s a longitudinal section of the turn-table brake; Fig. 8 is an inverted plan view of the cabinet and Fig. 9 is a vertical sectionon line a:-w of 8 with theposition of the cabinet reverse 1 is the. table upon which the usual talking machine rests. 3 is'a bracket secured to the rear of the talking machine which supports the removable arm 4 which in turn carries the sound box 5 which operates upon the disc 15 supported on the turn-table 7 and centered by means of the pin 6. v 6 is the handle for operating the motor of the machine. 8 is a horn section carried by the bracket 3 and communicating with the sound arm 4. The parts 4 and -8 together constitute a sound passagewa extending from the sound box. Supporte on top of the machine 2 is a cabinet divided by a horizontalpartition 12 into two compartments, the' lower compartment 13 enclosing the rotating disc and sound box, and the upper com- .partment being divided by partitions 10, 11,

'11 into a tapered amplifier, the small end of which opens at the rear through the back of the cabinet and communicates with the.

portion 8 of the sound passageway which may be connected with the rear of the cabinet by means of the clamp 18-19, which as shown is made in two sections connected by screws 20.

The walls 10, 11, 11 and 12 which exten from the rear opening to th front of the cabinet form a tapered amplifier which" opens at the front of the cabinet through adjustable doors 32 which may be adjusted by suitable handles 35, and there are thus formed between the side walls of the cabinet and the side walls 11,-

11 of the amplifier, resonance chambers 16-17, and the side walls of the cabinet are provided with doors 36-37, by the adjustmentof which, as shown in Fig. 8, the,

resonance chambers may be adjusted and,

outlets may be provided at the front.

Between the top of the amplifier 10 and the top 9 of the cabinet is also formed a resonance chamber 14, and this may be used,

if desired, as'a storage space for records 15,

arm 4 extends. a The plate is held in posi tion with freedom of movement by springs 2-1 between pins 26 on the plate and 25 on the frame of the cabinet. The movement of the plate may be regulated by the ad- .justment of the tension of the springs 24,

so that the arm may move freely while keeping the aperture 22 substantially-closed.

38 is a brake extending through an escutcheon 42 in the back of the cabinet and provided 0111 118 end with a friction pad 41 of leather, felt or equivalent material adapted to make contact with the periphery .of the turn-table. The brake is provided with a spring 40 between the pin 39 and the escutcheon, and the latter is provided with an elongated slot 43 so that when the pin is turned into the transverse position it. will be held retracted out of contact with the turn-table.

The lower compartment 13 of the cabinet is provided at the front with doors30 which may be opened, closed or adjusted to control the emission of sound from said lower compartment. The cabinet is preferably made separable from the body ot the machine 2 and may be attached by the clamp 28 and I set screw 29 as shown inFig. 1.

. ment of the cabinet.

This amplifier is formed in two sections, one of which is movable and the other fixed. In the particular construction shown the movable member is the lower portion 4 which moves with the sound box over the record, while the fixed portion is the up er part 8 which is attached by the brac et 18-19 to the upper part of the cabinet. The parts 4 and 8 constitute a means 0f com-. munication between the sound reproducing means and sound amplifyinguneans extending outside of the cabinet and comprising a fixed hollow member and a movable hollow member communicating therewith.

The walls of the amplifier are enclosed ,in a. resonance chamber or chambers i which may be opened, closed or adjusted by the re ulation of the enclosing walls. While I prefier the details of construction shown they may be varied without departing from the invention.

This application is filed as a division and continuation of myapplication Serial No. 411,454, filed January 18, 1908.

What I claim is as follows:

f' v1. The combination with sound re roducing means, of a co-operating ampl1 er,

a cabinet enclosing the major portion of said amplifier and provided with an penin of substantially the same size as the de ivery end of said amplifier, and means to vary the quality of the reproduction at will on either side of said cabinet.

2. In a talking machine, the combination of a cabinet provided with a sound chamber, sound reproducing means carried by said cabinet outside of said chamber and communicating with said chamber, and a pair of inflexible doors in said cabinet controlling the exit of sound.

' pair of inflexible doors. in said 3. In a talking machine, the combination of a cabinet provided with a chamber, sound reproducing means carried 'by said cabinet outside of said chamber, an amplifier en closed within said chamber and communieating with said reproducing means, and a cabinet for controlling the exit of sound.

4. In a talking machine, the combination of a cabinet provided with a sound chalm ber, sound reproducing means carried by said cabinet outside of said chamber and communicating with said chamber, and a plurality offswinging inflexible deflectors connected to said cabinet and controlling the exit'of sound from said chamber.

5. In a talking machine, the combination of sound reproducing means, a sound amplifier communicating therewith, and two swinging inflexible deflectors adjacent the mouth of the amplifier controlling the amplified sound.

6. In a talking machine, the combination of a cabinet, sound reproducing means carried by said cabinet, a sound amplifier communicating with said reproducing means with a sound reproducing means, of a 'cooperating amplifier, a cabinet enclosing the major portion of said amplifier and provided with a plurality of separated, resonance chambers between the enclosing walls of the cabinet and the walls of -the amplifier.

9.

12. A cabinet for talking machines .divided into two chambers, the lower chamber chamber of said cabinet, and 'a sound con-1 duit leading outside of the cabinet. from the sound reproducing means in the lower the upper chamber, and consisting of two hollow portions one of which is movable with respect to the other.

13. A cabinet for talking machines divided into two chambers, the lower chamber being open at the bottom and adapted to enclose the sound reproducing means, and

the upper chamber containing a sound am plifier and having adjustable side walls by which the space between the side walls of the amplifier and the enclosing walls of the chamber may beadjusted, in combination with a talking machine having its sound re- ,ber. chamber thereof to the sound amplifier in producing devices enclosed by the lowler chamber of said cabinet, and a sound conduit leading outside of the cabinet from the sound reproducing means in the lower chamber thereof to the sound amplifier in the upper chamber, and consisting of a movable hollow portion connected with the sound reproducing means and extending out of the lower chamber, and a fixed hollow portion connected with the small end of the sound amplifier in the upper cham- 14. A talking machine mechanism comprising a motor casing having a top provided with an outwalrdly extending and overhanging top portion, and a cabinet having its lower edges resting upon said top, fastening means upon said cabinet, engag-- ing with and beneath said overhanging top portion, and sound reproducing and conveying means extending outwardly from'within said cabinet. v
